I've only had them maybe 6 months, too - but they've at least doubles in size (the smallest one..) . They have really perked up over night and are chasing the tiger barb all over the tank. - took these pics of my phone so they are not the best - but it is sad when your PHONE takes better pics than your digital camera. 
BTW, those are mysis shrimp you see...
Are you my mommy?:
One of my older loaches in main tank (trying to hide):
they are looking good. i hope they settle in well when they get in their proper home with your bigger ones.
